CELL PARTS YEARBOOK PERIOD 1 2011-2012 • Favorite Hang-Out Spot: In between cell membrane and nucleus, can vary. • Hobbies: Generates energy for the cell through respiration • Extracurricular Activities: Nearly all eukaryotic cells • Siblings: Can vary, one to several thousand Kiera Beatty Cell Membrane Favorite Hang- Out Spot: Outer part of the cell Hobbies: Structural support, protection from outside molecules, transport in and out of cell, communication between cells Extracurricular Activities: Prokaryotic Cells, Eukaryotic Cells, Animal Cells Siblings: 1 Marianna Conserva Period 1 Lysosome Favorite Hang-Out Spot Near the outside of the cell Hobbies Breaking down waste materials in cells (ex: excess/worn out organelles, food particles) Extracurricular Activities Commonly found in animal cells Rarely found in plant cells Siblings Varied, depending on type of cell and function Emily Fang Ribosome~ Favorite Hang-Out Spot: He usually likes to hang out, suspended in the cytosol or bound to the endoplasmic reticulum. Hobbies: He is the sites of protein synthesis, where he translates RNA into protein. And when cells need large numbers of proteins, they come to Mr. Ribosome for help. Extracurricular Activities: This cell can almost be found anywhere around cell town he is found in only living cells. He is found in animal cells, and plant cells. Siblings: This cell was lucky to have so many siblings. That he has approximately 15,000 ribosome brothers and sisters in one cell! Can Be Found: Towards the outside of the cell hanging out with ribosomes, lysosomes, and mitochondrion. Chills underneath the nucleus. Hobbies: Modifying, sorting, and packaging proteins and other endoplasmic reticulum for storage within a Cell, or secretion to the outside of the Cell. Extracurricular Activities: Working universally in all plant and animal cells. Siblings: Animal cells generally contain between 10 and 20 Golgi stacks per cell. Plant cells can contain as many as several hundred smaller versions. Hitchings-Golgi Body T.J. Hitchings P.1 Name: Vacuole Distinguishing traits: Vacuolar membrane/tonoplast (cytoplasm membrane) separating vacuole contents from rest of cell. Regulates materials entering/exiting vacuole Favorite Hang-out: Near the middle of the cell Hobbies: Store food and nutrients and other things cells need for survival. Also stores waste products and water. Plants retain rigidity by increasing pressure/amount of water in vacuole (plants wilt if vacuoles are not filled). Can occupy anywhere from 30-95% of plant cell. In animal cells, stores waste to keep rest of cell uncontaminated (to be disposed of outside the cell later on) and aids in exocytosis (disposing of proteins/lipids from inside cell). Extracurricular Activities: All plant cells and certain types of animal cells (Much larger in plant cells than in animal cells). Siblings: Plant cell: None, only child. Animal cell: Usually none, but amount varies. Crystal Lee Pd. 1 Vesicle • Siblings (types of vesicles): -Vacuoles (Vesicle which contains mostly water) -Lysosomes (Involved in cellular digestion) -Secretory Vesicles (Contains materials that need to be excreted from the cell) -Transport Vesicles (Moves molecules around cell) • Hobbies: -Store, transport and digest cellular products and waste • Hang-Out (Where it can be found it cell): -Can be found anywhere inside the cell because it often has to move throughout the cell to do its job -----------Plant Cell • Extra Curricular Activities: -Plant cells often have a large central Vacuole -Found in almost all Plant and Animal Cells Jonathan Pearson Orlando period 1 Centriole Centrioles are the center of microtubules: 9 bundles (3 per bundle) of microtubules arranged in a ring Favorite Hang-Out Spot: Inside centrosome, which is condensed and darker area of the cytoplasm. They are positioned so that they are right angles to each other. Centrosomes are near the nucleus. Extracurricular Activities: Centrioles are found in all Animal cells only. Siblings: normally 2, but during cell division, 4 Hobbies: • They help with the cell division, both mitosis and meiosis. 1. At first, the centrioles remain together, but as mitosis/meiosis goes on, the original centrosome divides and the pairs are split up so that one set of centrioles is located in each of the new microtubule-organized centers. 2. They move to opposite ends of the nucleus and mitotic spindle appears. 3. Mitotic spindle connects to the chromosomes, they split, and are pulled towards each centriole. 4. The cells begins to split, and nuclear begins to appear. • Centrioles stay hidden from view when the cell is not dividing. Midori Uchibayashi Period1 Chloroplast •Hang Out Spot: Chloroplasts float around in the cytoplasm of the cell, they do not have a specific location •Hobbies: Chloroplasts job in a plant cell is to use photosynthesis to absorb energy from the sun and make sugar and starches for energy and food. It also contains chlorophyll that gives plants its green color. •Extracurricular Activities: Chloroplasts are found in any organisms that use the process of photosynthesis which is basically just plants. •Siblings: Varies- single-celled plants have one large chloroplast, other cells contain 20-100 chloroplasts. Naila Usmani Period 1 Microfilament- Gabe Favorite Hang-Out Spot: Microfilaments are the smallest filament in the cytoskeleton which exists in the cytoplasm of a cell. Because cytoplasm fills 54% of the entire cell, the microfilaments are found all around the cell. Hobbies: Microfilaments help the cell move with their versatile shape. This function is called amoeboid movement. Extracurricular Activities: Microfilament is part of all eukaryotic cells, meaning it exists in species with large and complex organisms such as fungi, animals, and plants. Siblings: It is impossible to count the number of microfilaments in a cell, as there are so many. What can be said is that they are an aspect of the cell that make up 54% of its mass. It is the combination of all of these microfilaments working together that allows a cell to move as it does. Gabriel Yoder-Shenk, P1 Intermediate Filament Favorite Hand out spot: Connected to the inner parts of the cell also connecting to other cells Hobbies : Resist pulling forces on the cell Extracurricular Activities: Animal Cells that require a lot of strength Siblings: Multiple depending on the cells Justine Dowling Pd. 1 Name: Vacuole Distinguishing traits: Vacuolar membrane/tonoplast (cytoplasm membrane) separating vacuole contents from rest of cell. Regulates materials entering/exiting vacuole Favorite Hang-out: Near the middle of the cell Hobbies: Store food and nutrients and other things cells need for survival. Also stores waste products and water. Plants retain rigidity by increasing pressure/amount of water in vacuole (plants wilt if vacuoles are not filled). Can occupy anywhere from 30-95% of plant cell. In animal cells, stores waste to keep rest of cell uncontaminated (to be disposed of outside the cell later on) and aids in exocytosis (disposing of proteins/lipids from inside cell). Extracurricular Activities: All plant cells and certain types of animal cells (Much larger in plant cells than in animal cells). Siblings: Plant cell: None, only child. Animal cell: Usually none, but amount varies. Crystal Lee Pd. 1 Lauren Schwartzman The Cell Wall The Cell wall enjoys his activities as a body guard for the elite Plant cell school. He never works for petty animal cell school. He has very important functions in the school and you could even say he is the Structure of the Plant cells in the school. He always loiters around the outside of the school. He is an only child. Matt Duffy Pd1 The Plant Cell The cell Wall Nucleus Centrosome By Matthew Wachira Favorite Hang-Out Spot • • It directly surrounds the cytoplasm surrounding the centrioles. Cytoplasm is the liquid/jelly like substance that fills up the "space" in any type of cell. A centriole is a barrel shaped organelle found in most animal eukaryotic cells. • Hobbies • Serves as the main microtubule organizing center (MTOC) of the animal cell. • Centrosomes are composed of two orthogonally arranged centrioles. • Centrosomes are associated with the nuclear membrane during prophase of the cell cycle. • Microtubules carry out a variety of functions, ranging from transportation to structural support. Siblings • There are usually a pair in each cell. Extracurricular Activities • It is found in Animal/Plant cells. Wachira, Matthew Period 1 Michael Foley Pd:1 Caitlin Simone Period 1 Microtubule Favorite Hang-Out Spot: Typically found in eukaryotic cells, as part of the cytoskeleton. (Near the outside of a cell) Hobbies: transport and structural support of a cell. They maintain the cytoskeleton, that is, the basic structure of the cell. They are involved in cell movement, cell shape and the formation of mitotic spindles during cell division (mitosis) Extracurricular Activities: Found in animal cells and plant cells. Siblings: Axoneme ( microtubule assembly) There are about twice as many microtubules as there are centrosomes in a cell. LaDell Bligen Period:1 Nucleoplasm • The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane or nuclear envelope. • The nucleoplasm is a highly viscous liquid that surrounds the chromosomes and nucleoli. • Many substance such as nucleotides and enzymes are dissolved in the nucleoplasm. • A network of fibers known as the nuclear matrix can also be found in the nucleolpasm. The soluble, liquid portion of the nucleoplasm is called the nuclear hyaloplasm. QuickTime™ and a decompressor are needed to see this picture. QuickTime™ and a decompressor are needed to see this picture. • Nucleoplasm is found under the inner layer • Also it is found in the Nucleus • Nucleoplasm is found in both plants and animal cells • Only found in cells with a Nucleus Justin Bauter Biology Period 1 Nucleoplasm - Orlando • Cytoplasm is a gel-like substance residing between the cell membrane holding all the cells internal substances. In prokaryote cells all contents of the cell are contained in the cytoplasm. In eukaryote cells the contents of the cell nucleus are separated from the cytoplasm. • It is within the cytoplasm that most cellular activities occur, like cell division. It is also where the functions of cell expansion, growth, metabolism, and replication are carried out. • Cytoplasm is made up of cytosol, organelles, and cytoplasmic inclusions. Cytosol is a translucent fluid in which the plasmic elements are suspended. The organelles are the “organs” inside the cell that are suspended in cytosol. The inclusions are small particles of insoluble substances suspended in cytosol. • Cytoplasm is found in both plant and animal cells. And it is found throughout the entire cell. Adam Gostomski PD.1 Smooth Endoplasmic Reticulum • • • Located just outside the nuclear membrane The smooth endoplasmic reticulum has had several jobs in his high school years including several metabolic processes, which are synthesis of lipids and steroids, metabolism of carbohydrates, regulation of calcium concentration, drug detoxification, attachment of receptors on cell membrane proteins, and steroid metabolism. Tends to hang out in both plant and animal cells • He has no siblings being that there is only one of them found in a cell
